AUTOMATIC APPARATUS FOR SEGREGATING RETURNED BOWLING BALLS" Oct. 1, 1963 3 Sheets-Sheet 3 Filed June 13, 1960 INVENTOR. tfofzn afiei'eclfd States This invention is directed to an automatic device having two separate longitudinal spaced apart racks adapted to segregate and separately receive returned bowling balls from the respective alleys on which the balls were played so that the balls played on one alley will be delivered to a separate rack and balls played on an adjacent alley will be delivered to a second and separate rack. More particularly, this invention is directed to an electro-mechanical automatic ball returning and ball segregating device for bowling alleys.

The conventional bowling alley uses one ball return track and one rack for each pair of adjacent alleys. Since the balls played on both alleys are returned to a single rack in no practical order, the balls become mixed up, thus requiring each bowler to examine an indefinite number of balls in order to determine which ball is his.

It is an important object and accomplishment .of my invention to provide an automatic device for returning and segregating the respective balls played upon adjacent alleys to mount and position the balls played on one alley on one separate specific rack, and to return and position the balls played on a separate and adjacent alley upon a second and separate rack, so that the balls played upon one particular alley will always be returned to and positioned on a separate rack so that the ball in the last and foremost position on one particular rack is always the ball belonging to the next bowler who is playing on the one specific alley Whose balls are returned to the specific positioning rack which receives only the balls played on one alley. For example, the ball returned to the last position on a separate rack 11 is always the ball belonging to the next bowler to play on alley 10.

Where a particular bowler makes a spare, for example on alley 10, his ball to be used by him as his second ball to be thrown will be the first ball positioned on rack 11 where he is playing and the alley designated as No. 10. Similarly, the ball used for the first throw on alley No. 9 and to be used by the same bowler for his second throw to make a spare will be returned to the front position of rack No. 20 where the :bowler is using right alley No. 9.

It is an important object and accomplishment of my invention to provide a novel automatic apparatus and mechanism including a ball return track which includes two separate longitudinally spaced apart elevated ball receiving and positioning starting racks, and which includes automatic means and mechanism which will cause the bowling balls played on one particular alley to be returned and positioned upon one of said racks; and which will cause the balls played on another and adjacent alley to be returned and positioned on the other and separate starting rack.

It is a further object and accomplishment of my invention to provide an automatic device for returning and positioning bowling balls played on separate alleys to separate and different ball-receiving starting racks so that the balls played upon each of said separate alleys will be returned to and positioned on separate spaced apart starting racks, so that the respective players on one of said alleys will be able to easily select and pick up their respective balls from a starting rack separate and apart from the starting rack which receives and positions the bowling balls which are played on the other and normally adjacent alley.

It is a further object of my invention to provide devices as described in the preceding paragraphs and which include a pair of separate ball-receiving racks and an electrically actuated normally inclined pivoted chute for causing balls to return to one of said racks, and electrically actuated switches and mechanism for selectively positioning and holding said pivoted chute in supported position to effect return of the balls played on one specific alley to one of said racks.

Other and further important objects of my invention will be apparent from the following description and claims.

On the drawings:

Referring to FIGS. 1 and 2, numerals 9 and 10 designate right and left bowling alleys respectively, of usual construction. Numeral-s 12 and 13 design-ate right and left spaced apart parallel vertically extending boards or rails which form a ball return track and which are suitably secured by screws 17 to said alleys 9 and 10. These are so spaced so that conventional bowling balls will roll thereon.

Numeral 14 designates an upwardly extending inclined end member which forms a continuation of the two track rails 12 and 13 and which forms an inclined trough down which the balls are adapted to roll onto the return track. As shown in FIGS. 1 and 2, numeral 16 is an inclined return chute formed of two strips connected to end memher 14 upon which the balls played on left alley 10 are deposited by an automatic pin setting and ball returning machine (not shown).

Numeral 15 designates an inclined right return chute formed of two bars or strips and connected to the end member 14 and on which the halls played on the right alley 9 are adapted to be deposited by an automatic pin setting and ball return-ing machine (not shown), said delivery being at a different time than the delivery of balls upon the chute 16. Said chutes 16 and 15 are inclined or sloping downwardly to the trough of the end member 14 so that the balls will roll by gravity into said trough and then downward onto the return track.

Referring to the right side of FIG. 1, numeral 11 designates a ball return and positioning rear pack which is preferably composed of two relatively wider panels or strips which form a continuation of the rear portion of the return track, and which have forwardly curved portions on which the returning balls roll slightly upwardly to then be stopped on the rear rack by either the stop plate 18 or by balls on said rack. Numeral 19 designates a U-shaped ball snubber or saddle whose legs are secured by screws to the opposite faces. of the rack 11.

As shown in FIGS. 1, 4 and 5, numeral 20 designates an intermediate or forward ball rack which is supported by four legs 21 upon the floor over the intermediate portion of the ball return track, and which includes a pair of spaced apart bars onto which the balls will roll. A stop plate 22 is suitably secured to the rear end of rack 26 and which will stop the balls rolling on said rack. Numeral 23, in FIG. 1, is a U-shaped snubber secured on the forward end portion of rack 20 and the upper pm of which is frictionally engaged by the balls entering said rack to slow the balls.

As shown in FIGS. 4 to 7, nurner-atl 24- designates a trough-like tiltable chute which has a pair of angularly and downwardly extendmg apertured cars 25. A horizontal pivot pin 26 extends through said cars and its opposite ends are suitably mounted in holes in the lower edge portions of the two track rails 12 and 13 at points below the upper edge of said track. The upper end of said tiitable chute 24 is slightly bent rearwardly, as illustrated in FIGS. 4 and 5, and terminates a short distance forward of the forward end of ctront rack 20. A counterweight 27 is secured on the lower part of chute 24 to cause it to normally tilt upwardly. Numeral 28 designates a stop block or bracket suitably secured to track rail 13 and which limits the upward tilting of said chute 24.

As shown in FIGS. 4 and 5, a solenoid 32 is suitably mounted to said track rails 13 below its upper edge and it has connected to it circuit wires 55 and 72 herein-after described. The apertured end of the core 33 of said solenoid is pivotally connected by a cross pin 34- to the lower slotted end of a support lever 29. Support lever 29 is fulcruInmed on a horizontal cross pin secured in the track rails 12 and 13. The upper end of lever 29 carries an upwardly curved arcuated dog or plate 31 whose forward edge is adapted to be engaged by the rear end of chute 24 to support said chute when said lever is in forward position, as shown in FIG. 4.

Referring to FIG. 2, numeral 65' designates an electrical switch secured by screws to one of the inclined bars of delivery chute 15. A pivoted flexible metal arm 67 is mounted on said switch which contacts terminal 63 when said spring arm 67 is depressed by a ball rolling down said delivery chute. Circuit wires 66 and 67a are connected to said spring arm 67 and to the terminal 68 of said switch and their other connections are hereinafter described.

It is understood that the presently known pin setting machines which pick up the pins and also pick up the bails each have an automatically elosatble door or gate mounted on the discharge opening through which the balls are delivered from the machine to inclined delivery chutes such as ill-ust-nated by numerals in FIGS. 1 land 2. Further, such discharge gate of each such machine is electrically operated, locked and unlocked and the electrically operated gate control mechanism of one machine is operatively connected to the gate contnol mechanism of the adjacent machine, which machine picks up balls for delivery to the same return track in such a way that when one of the two machines discharges a ball and opens its outlet gate, the gate of the other adjacent machine will remain locked and prevent the simultaneous discharge of a second ball from the second machine. This prevents two balls from being discharged on the return chute at the same time and prevents the possibility of two balls closely following each other on the return chute; and thereby keeping the returning balls adequately spaced apart.

In FIG. 3a is illustrated a novel switching device which is mounted below the return track in a position a substantial distance rearward of the inclined delivery chutes 15, 16 to the rack 20, and is generally designated by numeral 4.

The distance of the switch device 4 from the delivery chutes 15 and 16 is such that a ball delivered from chute 16 onto the return track will have passed open switch 4 before another ball rolling upon chute 15 will actuate control switch 65. The balls delivered from said chute 16 will continue rolling along the return track and over open switch device 5 and onto the rear ballrack 11.

Referring to FIG. 3a, numeral 36 designates a solenoid secured on track rail 13 and between track rail 13 and track rail 12. The core of said solenoid 36 has secured to its outer end one end of a vertically extending metal bracket 38 whose upper terminal end has connected to it one end of a circuit wire 41'; Said bracket 33 has as slot in its central portion. A curved metal trip lever 45 has its lower end pivoted on apin' 46 so its upper end will project slightly above the upper edges of the return track so it will be engaged by a rolling ball.

Trip lever 45 carries an intermediate cross pin. or stud will cause it to contact terminal 40 to close the circuit between wires 44 and 41. In FIG. 3a said circuit is shown open and the core drawn into the solenoid and the bracket 38 pulled to left position in which trip lever 45 is adapted to be pivoted by engagementof a ball.

Another and second switching device, generally desig-,

nated by numeral 5, which is similar to that shown in FlG. 3a, is illustrated in FIG. 3b and is suitably mounted below the upper edge of the rails 12 and 13 which form the ball return track and intermediate the rack 20 andthe previously described switching device 4 .shown in FIG. 3a. The switching device 5 is positioned rearward along the return track a sufficient distance so that each ball which has been delivered from chute 16 will have passed said switch device 5 before a following ball from chute 25 has reached and activated switch device 4 and.

consequently actuated switch device 5.

Switching device 5 comprises a solenoid 50 having circuit wires 41 and 51 connected to it; and a movable core 7 on which is mounted upwardly extendingbracket 52 on whose upper end is terminal screw 54. Bracket 52 has a central slot as shown. Lever 59, which carries an up per pawl 61, is pivoted on a pin 63 secured in one of the rails 13, and said lever has a transverse pin 62 which extends through the slot of bracket 52.

Numeral 56 is a block secured on rail 13 and has secured thereon by screws a flexible metal contact spring 57, whose secured end has connected to it circuit wire left from the position shown in FIG. 3b so that when a 7 ball rolls along said track it depresses contact spring 57 to contact it to terminal 54 to close the circuit which energizes solenoid 32 (see FIG. 5), to thereby pull rear wardly the core 33 and lower part of support lever 22.

This causes the lever 32 to move counterclockwise to the.

supporting position shownin FIG. 4 in which position it supports the free end of inclined chute 24 to cause the returning ball to roll up chute 24 onto rack 20.

As the ball has rolled past spring 57 in its return travel, it strikes pawl 61 to cause said lever 59 to pull the core and the bracket 62 outward to a non-contact position, as illustrated in FIG. 3b.

Description of Circuits One terminal of control switch 65 on the delivery chute 15 is connected by wire 66 to a source of electric power, which is preferably a transformer 70, illustrated at the left of FIG. 6. Circuit wire 66 is connected by a wire 44 to the terminal of the contact spring 43 of switch device 4. A wire 58 connects wire 44 and one terminal of contact spring 57 of switch device 5.

The other terminal 68 of control switch 65 is connected by a wire 67a to the solenoid 36. A wire 41 connects terminal 49 of bracket 38 to one terminal of solenoid 50 of switch device 5. Wires 37, 72 and 51 connected together connect one terminal of solenoid 36 to one terminal of solenoid 50.

Wire 71 connects the transformer 76 to wire 37 and to solenoid 36. Wire 72 connects wire 37 and 71 to wire 51 and also connects wire 51 to one terminal of the solenoid 3'2. Wire 55 connects the other terminal of solenoid 32 to the terminal 54 of the bracket 52 of switch device 5.

When a ball is bowled in the usual manner on the right-hand alley 9, it is then picked up by the pin setting and ball pick-up mechanism and delivered upon the righthand inclined chute 15. As the ball rolls down said chute it depresses contact spring 67 to close a circuit between said spring 67 and terminal 68 of switch 65, to thereby close the circuit of said switch. As said circuit is connected to the solenoid 36 of switching device 4, shown in FIG. 3a, through wires 67a, 71 and 37, the coil of solenoid 36 is energized to pull inward its core and the bracket 38 and terminal 40. This causes the trip lever 45 to be rocked counter-clockwise or pivoted to the left and to cause its upper end and pawl to project above the upper edges of the rails of the return track. This causes the terminal 40 to be positioned below the free end of the contact spring 43.

When the returning rolling ball moves above the contact spring 43 the ball presses down said contact spring 43 to contact terminal 40, this closing the circuit of the wires 44, 58 and 41 (which circuit controls the coil of solenoid 50). Said closing of said circuit causes the solenoid 50 to be energized to thereby pull inward and to the left the core of said solenoid and the bracket 52 and its upper terminal 54, to thereby position said terminal 54 below the free end of the contact spring 57. At the same time, the trip lever 59 and its upper pawl 61 are moved upwardly and to the left to position the pawl 61 above the edge of the track.

The rolling ball, in its continuing return travel, pushes pawl 61 rearwardly to position switch device in open position and depresses contact spring 57 to cause it to contact terminal 54 and close the circuit thereof and also to strike and move rearwardly and to the right the pawl 61 and lever 59 and to thereby pull outwardly the core and the bracket 52. As the contact spring 57 contacts the terminal 54 the circuit thereof, which is connected to solenoid 32, energizes said solenoid 32 to cause the core 33 to be-pulled inwardly to thereby rock the lever 29 counter-clockwise to the full line position illustrated in FIG. 4, and in which position it will temporarily support the free end portion of chute 24 against downward tilting movement. When said chute 24 is supported by lever 29, the ball will roll up the chute onto rack 20 and, as it leaves the chute, it pushes lever 29 rearwardly to move said lever 29 in non-supporting position.

It is to be borne in mind that as the ball approaches the chute 24 counter-weight 27 holds the chute 24 in upwardly tilted position, so that when the lever 29 5 up said chute 24 and onto the ball rack 20.

It will be understood that the returning ball has returned the switch devices 4 and 5 to open position and will strike the curved plate 31 of trip lever 29 as it enters upon the ball rack 20 to also return said lever 29 townoperating right-hand position, as illustrated in FIG. 5.

If the succeeding ball, which has been played on the left alley 10, is delivered on the left hand chute 16, such ball will continue in its return travel along the return track while both of said switching devices 4 and 5 are open and inoperative and while the trip lever 29 is in retracted inoperative position, so that when the returning ball contacts the middle portion of the tiltable chute 24 it will tilt or pivot said chute downward to a plane below the upper edges of the track rails to cause the ball to continue in its straight return path underneath the rack 20 and to cause it to roll upon the rear ball rack 11.

Accordingly, all balls played on the left alley 10 and deposited for return on the left chute 16 will return to the rear rack 11 without the operation of any of said 25 switching devices, and in what might be called a free uninterrupted r'ide to said rear rack.

The ball which has been delivered down chute 15 and activated said switches must have passed switch 4 and opened said switch 4 and thereby de-energized the solenoid of switch 4 and moved the lever 45 into rearward non-obstructing position before a ball delivered off of left chute 16 can roll past switch 4 and past the retracted lever 45.

While in the preferred form I have illustrated and described the two separate ball positioning racks as being positioned one in front of the other, I desire to be understood that said separate racks may be in diiferent relative positions, for example transversely spaced from each other or substantially adjacent each other so long as one of said positioning racks is communicatively connected to receive returning balls from the return track and the other thereof is connected to receive returning balls which have been diverted by a movable pivoted chute.
